I'm trying to build a gstreamer pipeline to take snapshots (only on picture) from the camera. I'd like one for the N810 and one for the N900.

On the N810, I came up with :
gst-launch v4l2src num-buffers=1 ! video/x-raw-rgb,width=640,height=480,framerate=8/1 ! ffmpegcolorspace ! jpegenc ! filesink location=test.jpg

The pipeline is executed as it should, but the jpeg file is a black frame... I tested v4l2src ! ffmpegcolorspace ! xvimagesink to check the camera hardware and it's ok.

For the N900, I'd be grateful for any help since I don't have this lovely device yet ;-)

Thanks,

Fabrice

works on the n900 and produces a 640x480 jpeg from the front camera.

I'm puzzled by this:

Would you have a suggestion? Thanks in advance.
